Well the "processes" page of the gnome-system-monitor application seems to show very faulty data. The diskread total and diskwrite total for any application is "N/A" (even though I know certain applications save to disk, and I am trying to debug this, since disk seems to constantly run & seem to lag down the whole system).
On top of that the actual cpu usage is always "0" for any application, yet in the "resources" tab I see total cpu be somewhere around 20-40%.
What is causing these problems and how can I fix it to find which process is keeping my hard drive busy?
On request here is a log of the system monitor while webstorm is loading (and I actually hear the hard drive being busy, and cpu is also not zero). The process marked (java) is what corresponds to webstorm ide: which is actively loading.
I'm using ubuntu 18.04
